CABLE-OPERATING DRUM.

Specification of Letters Patent.

Application filed March 14, 1910. Serial No. 549,180.

To all whom it may concern:

Be it known that I, JOHN N. ANDERSON, a citizen of the United States, residing at Madison, in the county of Dane and State of Wisconsin, have invented certain new and useful Improvements in CableOperating Drums, of which the following is a specification.

My present invention relates to pulle s or drums of that character which are utllized to ive movement to an endless cable or the like, the pulley or drum receiving the cable thereabout and giving such movement by its rotation.

The object of my invention is to provide a simple and inexpensive tpulley which will be durable and lasting an which will have a non-slipping cable surface, and a further rovide means to adjustably mount the u ey.

With this-in view my invention resides in the features of construction and arrange ment to be hereinafter-described with reference to the accompan in drawing, formin a part of this s eci cation, and in which,

.igure 1 is an ge .view, partly in section, of the Ipower pulley or drum and its mount ing. ig. 2 is a front elevation of the frame wlth the pulley or drum removed, and, Fig. 3 is a face view of the pulley or drum, part y in section. I

Referring now to these figures, 10 re re sents my improved pulley or drum an 11' represents the frame to which the same is to be mounted, this frame 11 havin an under cut vertical slot 12 into the un er-cut of which fits the headed inner end 13 of an outstanding bolt 14, said bolt having a threaded outer end 15 and being, of course, adjustable up and down throughout the length of slot 12 when frame 11 is secured upon a suitable support A. The bolt 14 may be secured by means of a nut 16 upon its threaded end 15, which nut thus engages the outer end of a sleeve 17 upon said bolt, and which sleeve in turn bears at its inner end, against the surface of frame'll, thus binding the bolt in selected adjustment.

The pulley or drum 10 is mounted upon sleeve 17, and prevented from displacement by nut 16, and comprises a wooden core 18 and a pair of flanged metal-face plates 19, the flanges of which extend partially over the periphery of said core and leavea central exposed portion into which are driven a series of studs 20, the outer concave ends of which form a traction surface for the operating'cable, and one which will prevent the cable from slipping.

While thispulley or drum may, of course, be driven in any suitable manner, I have shown the same as provided with a crank 21 for manual rotation.

I claim:

1. A cablepulley or drum comprising a core, face plates secured to said core, and

platessecured upon the sides of said core and having their flan es extending partially over the peri hery t ereof, and a circular series of stu s projecting from said core between said flanges and having concave cable-engaging ends.

a In testimony whereof I afiix my signature in presence of two witnesses.

JOHN N. ANDERSON.
